建立Jakes模型，生成Rayleigh信道。以此为基础，研究不调制，及DSPK等方式的调制下，均衡技术（尤其是迭代均衡）的给误码性能带来的增益。(To build the Jakes model,we can get the Rayleigh channel,on the basis of which we study on the benefit of equilization(Iterative equilization specially) in DSPK modulation.)

Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet digital communication systems. A simple form of MD is the camer phase exp GO) which has to be estimated and compensated for in a coherent receiver. A more general case with fading must, however, allow for amplitude as well as phase variations of the MD. We assume a state-variable model for the MD and generally obtain a nonlinear estimation problem with additional randomly-varying system parameters such as received signal power, frequency offset, and Doppler spread. An extended Kalman filter is then applied as a near-optimal solution to the adaptive MD and channel parameter estimation problem. Examples are given to show the use and some advantages of this scheme.
